A Statistical Analysis of Some Experiments on Slipped Tendon

MANY suggestions have been made by various workers concerning the cause of a malformation of the leg bones of chicks commonly known as slipped tendon. Several conflicting opinions have been presented. The writer has attempted a statistical analysis of the literature of the field, in order to ascertain whether or not there is any constant relationship between certain constituents of the ration and the incidence of slipped tendon. METHOD OF ANALYSIS The data here analyzed are taken from the work of Hunter and Funk (1931), Payne, Hughes, and Leinhardt (1932), Titus (1932), and Mussehl, Ackerson, and Blish (1927). The work of the latter was not on slipped tendon, but a condition of “typical rickets” which developed in one lot that was irradiated is described. The description of the malformation indicates that it might represent the condition known as slipped tendon. Four other lots in this experiment are also used in . . .
